摘要:

在2种模拟人体胃液条件下,采用分光光度法测定不同质量浓度的黑糯玉米色素及不同反应时间对亚硝酸钠的清除能力和对亚硝胺合成的阻断能力,并与VC进行比较。结果表明:随反应质量浓度提高,黑糯玉米色素对亚硝酸钠的清除能力和阻断亚硝胺合成能力有明显提高,不同的反应时间、模拟人体胃液条件下效果有一定差异。在模拟人体胃液B条件下,色素质量浓度为0.10mg/mL,时间为1h时对亚硝酸钠的清除率达到81.37%,对亚硝胺合成的阻断率达到57.03%。通过与VC的对照及分析,得出黑糯玉米色素具有较强的清除亚硝酸钠和阻断亚硝胺合成的能力。

Abstract:

The influence of pigment concentration and exposure time on the effectiveness of pigments from
black glutinous corn (PBGC) to eliminate nitrite and block nitrosamine synthesis was investigated in two kinds
of simulated human gastric juices and the results obtained were compared those of VC. At higher concentrations,
PBGC was more effective in eliminating nitrite and blocking nitrosamine synthesis. Both activities varied depending
on reaction time and different simulated gastric juices. In the simulated gastric juice B, 81.37% of the nitrite was
eliminated after 1 h of expoure to 0.10 mg/mL PBGC and nitrosamine synthesis was blocked by up to 57.03% by
PBGC. Comparing it with VC, we concluded that PBGC have a strong capability of eliminating nitrite and blocking
nitrosamine synthesis.
